Did you ever wonder what occurs inside your body whensomething funny happens?
What is this thing we have in ourbrains that makes us say “ha-ha” when someone slips on abanana?
One way to find out is to watch the brain laugh.
That's whatDartmouth neuroscientist William Kelley did.
He and his team had a number of volunteers watchan episode of Seinfeld while being monitored by an MRI-that's a machine that allows researchersto see which parts of the brain are active at any given time.
They then synchronized the MRI datawith the laugh track to see how the brain changes when it's registering something funny.
There'sno one “funny center” in the brain–but the findings were pretty suggestive.
When subjects were looking at something funny, the two regions in their left hemispheres lit up.
From previous studies these regions are known to be associated with resolving ambiguity. Is theresomething in “getting it” that's related to the process by which we work with unclear informationuntil we suddenly see the pattern in it?
A couple seconds later two other brain regions became active, called the insula and the amygdala.The insula is associated with emotion, so it seems likely that this is the brain feeling good when itgets the joke–the “ha-ha” response.
The amygdala is associated with memory formation.
As the researchers point out, while you maynot be able to remember every plot detail in a Seinfeld episode, you can probably remember the jokes.
Humor stays with us, forming a lasting memory. Get it?
译文：
你有没有想过，当有趣的事情发生时，你的身体里会发生什么？
我们的大脑里有什么东西使我们在有人滑倒时说 "哈哈"？
找到答案的一个方法是观察大脑的笑。
这就是达特茅斯大学神经科学家威廉-凯利所做的。
他和他的团队让一些志愿者在核磁共振成像的监测下观看一集《宋飞》--这是一种允许研究人员看到大脑的哪些部分在任何特定时间都在活动的机器。
然后他们将核磁共振数据与笑声同步，以观察大脑在记录有趣事物时的变化。
大脑中没有一个 "搞笑中心"，但研究结果非常具有暗示性。
当受试者在看一些有趣的东西时，他们左半球的两个区域亮了起来。
根据以前的研究，这些区域被认为与解决模糊性有关。在 "得到它 "中是否有一些东西与我们处理不清楚的信息直到我们突然看到其中的模式的过程有关？
几秒钟后，另外两个脑区开始活跃起来，称为脑岛和杏仁核。脑岛与情绪有关，所以这似乎很可能是大脑在得到这个笑话时感觉良好--"哈哈 "反应。
杏仁核与记忆的形成有关。
正如研究人员所指出的，虽然你可能无法记住《宋飞传》中的每一个情节细节，但你可能可以记住笑话。
幽默会留在我们身边，形成持久的记忆。明白了吗？
